摘　　要：在分析基于电感饱和原理来获得表贴式永磁电机转子初始角方法的基础上,为解决传统方法不可靠、准确性低的难题,提出了电压矢量法,该方法在处理第二波电压矢量时,同时加入限制条件。而且在第二波电压矢量后,为了提高了电流峰值而延长了电压矢量的作用时间,这样就使得转子的增去磁效果更为显著,也增大各个矢量电流大小的差别,从而提高了检测结果的可靠性。实验结果表明该方法既确保了转子不发生转动,又大幅度增强了检测的可靠性。Based on the analysis of the inductor saturation effect, the voltage vector method of the rotor initial position angle estimate of surface mounted permanent magnet synchronous motor is proposed. To deal with the problem of unreliability and low accuracy in the conventional detection scheme of voltage vector, the reverse direction inductance is used to add constraints when handling the second wave of voltage vector, and the action time of voltage vector is increased to increase the peak current after the second wave of voltage vector. By raising the effect of demagnetization and enlarging the differences of each vector current, finally the reliability of initial angle detection is improved. The experimental results verify the feasibility and effectiveness of the the proposed method.
